Document Type and Number:
WIPO Patent Application WO/2022/085733
Kind Code:
A1
Abstract:
The present invention provides: an electrode composition which contains an inorganic solid electrolyte, an active material, a polymer binder that is configured to contain a linear polymer, and a dispersion medium, wherein the radius α of gyration of the polymer binder and the equivalent median diameter D50 of the inorganic solid electrolyte and the active material are inside (including the boundary line) of a polygonal region with vertices at points A to E in a rectangular coordinate system wherein the radius α of gyration is taken on the x-axis and the median diameter D50 is taken on the y-axis; an electrode sheet for all-solid-state secondary batteries and an all-solid-state secondary battery, each of which uses this electrode composition; a method for producing an electrode sheet for all-solid-state secondary batteries; and a method for producing an all-solid-state secondary battery.
